Title: Dynamic pressure type radial bearing device
Inventor: SUMIHIRO MASAKAZU
IPC: F16C17/02
Filed: 1986-04-17
Abstract: PURPOSE:To obtain smooth rotation of a revolving shaft, by forming a herring- bone groove into a narrow and tapered shape, thereby increasing the radial rigidity necessary to support the revolving shaft in the radial direction. CONSTITUTION:A herring-bone groove H is formed in such a manner that its groove-width is narrowed or taptered as it goes from the outsides (along the axial direction of a fixed shaft 5) toward the inside. The fluid dynamic pressure generated in a group 6 of the herring-bone grooves acts on the space between the outer peripheral surface of the fixed shaft 5 and the inner peripheral surface of a rotation shaft 7, thereby supporting the rotation shaft 7. Meanwhile, the fluid dynamic pressure generated in the spiral groove can support the rotation shaft 7 without making the shaft 7 touch the fixed shaft 5. Accordingly, since each groove H in a herring-bone groove group 6 is formed into a tapered shape, the fluid dynamic pressure P1 is generated, and the radial rigidity can be increased. In addition, smooth rotation of the shaft can be obtained.

Title: Modulating transformer and focus corrector
Inventor: SUZAKI SHOJI
IPC: H01F19/00
Filed: 1993-04-15
Abstract: PURPOSE:To modulate an AFC pulse with high accuracy by means of a modulated wave of a vertical period. CONSTITUTION:A drum type core 11 wound by a main coil 12 and a drum type core 13 wound by a secondary coil 14 are placed via a gap G as shown in a diagram. Then a current to be modulated is supplied to the coil 12 and a modulated current is supplied to the coil 14 respectively. Thus the inductance of the coil 12 is increased when the magnetic fluxes of the flange parts of both cores 11 and 13 set counter to each other via the gap G are set in the same direction. Meanwhile the inductance of the coil 12 is reduced when those magnetic fluxes are set in the different directions. Therefore the current to be modulated and flowing to the coil 21 can be modulated by the modulated current flowing to the coil 14. Under such conditions, the magnetic flux of the core 11 draws a loop via the flange parts of both edges and therefore scarcely enters the center part of the core 13. Thus the current flowing through the coil 12 is modulated with high accuracy.

Title: Constant speed travelling device
Inventor: MUTOU MASAHITO
IPC: B60K31/04
Filed: 1983-05-20
Abstract: PURPOSE:To prevent malfunction by actuating a regime function when a regime switch is depressed by the prescribed number of times. CONSTITUTION:A main switch 41 is turned on to supply a power source to a control circuit 2 and a computer 21 sets a car speed and controls an actuator 5 to control the car speed. If a break pedal is pressed during the control of car speed, a cancel signal is generated from a stop lamp switch 12. The cancel signal is inputted to the computer 21 through an OR circuit 24 to release the car speed control. In this case, the storage of the set car speed is not released. When the car speed becomes a value less than the prescribed speed, the car speed control is released in the same manner as said case. When the regime switch 44 is turned on twice after releasing the car speed control, whether the set car speed is stored or not is discriminated, and when the storage exists, the car speed control is restarted.
